BACKGROUND OF THE INVENTION

A seat is a piece of furniture with a raised surface supported by legs, commonly used to seat a single person. Seats may vary in their design and number of legs, though generally comprise a relatively horizontal surface having three to five relatively vertical legs for support. A seat further comprising a relatively vertical support surface may be known as a chair. Seats and chairs may comprise a variety of materials of construction, though are commonly made from plastics, metals, woods, or some combination thereof. Seats and chairs may be further padded or upholstered or may comprise removably attached cushions for additional user comfort.

A folding seat is a seat that folds upon itself into a more compact form so as to occupy less space. Such a seat may be mounted to a vertical surface and may articulate up or down, or may be unmounted and may articulate relative to its vertical legs. A folding chair may be designed so that a chair back and chair seat may articulate relative to one another, and may further articulate relative to the vertical legs or may incorporate the vertical legs into the articulating action. Most folding chairs articulate at the seat, forming a side-x design, wherein the chair back support and the front legs are the same component.

Such folding chairs and folding seats, though, do not fold down into a suitably compact form for ease of carrying by a user, especially a user that may be otherwise encumbered by goods, such as a parent or guardian with a child in a stroller. Therefore, there is a need in the art for a portable folding seat with cushion attachments that is sufficiently compact for ease of carrying onboard a stroller or within a baby bag, that may be attached to a stroller for sitting, and that is also strong enough to support a user while being padded for user comfort.

It is to these ends that the present invention has been developed.

The plurality of means for stroller attachment 216 may be any appropriate mechanism of attachment such as, for example, a post-receiving hole, a snap button, or a clip.

The upper surface of the main body 100 may comprise a plurality of means for cushion attachment 400 generally located along each lateral end of a front side and a rear side of the main body 100. The plurality of means for cushion attachment 400 may comprise button snaps, clips, hooks, or any other mechanism appropriate for such a purpose, and may reversibly attach a seat cushion. The plurality of upper legs 200 and plurality of lower legs 300 on a first side of the present invention may comprise a width wider than the plurality of upper legs 200 and plurality of lower legs 300 on a second side of the present invention so that the second combination may rest within the first combination when both combinations are folded.

The design of each various component may further comprise rounded, chamfered, beveled, or similarly modified edges for aesthetic purposes. The combination may further comprise a seat cushion 500 with cushion attachments, which may reversibly attach to said plurality of means for cushion attachment 400.

The portable folding seat with cushion attachments may be substantially constructed of any suitable material or combination of materials, but typically is constructed of a resilient material or combination of materials such that the device is resistant to damage as a result of compression, twisting, heating, or submersion in water. As an example, and without limiting the scope of the present invention, various exemplary embodiments of the portable folding seat with cushion attachments may be substantially constructed of one or more materials of fabric, plastic, acrylic, polycarbonate, steel, aluminum, brass, fiberglass, carbon fiber, or combinations thereof. In some embodiments the various components of the device may be coated, lined, or otherwise insulated to prevent contamination of the device. In one embodiment the material of construction may vary from one component to the next within the system.

In one embodiment the portable folding seat with cushion attachments may comprise a resilient material of construction that either comprises a material having antimicrobial properties or comprises a layering of antimicrobial material or coating. Antimicrobial properties comprise the characteristic of being antibacterial, biocidal, microbicidal, anti-fungal, anti-viral, or other similar characteristics, and the oligodynamic effect, which is possessed by copper, brass, silver, gold, and several other metals and alloys, is one such characteristic. Copper and its alloys, in particular, have exceptional self-sanitizing effects. Silver also has this effect, and is less toxic to users than copper. Some materials, such as silver in its metallic form, may require the presence of moisture to activate the antimicrobial properties.

While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
